, 2021 A decade of research has shown that the molecule c-di-GMP functions as a central second messenger in many bacteria. A high level of c-di-GMP is associated with biofilm formation whereas a low level of c-di-GMP is associated with a planktonic single-cell ...

T cells, the Next Big Target in Axial Spondyloarthritis?
Arthritis &Rheumatology, EarlyView.Axial spondyloarthritis (axSpA) is a chronic inflammatory disease characterized by complex immune dysregulation, with T cells playing a central role in its pathogenesis. In this review, we synthesize current knowledge on diverse T cell subsets in axSpA, their pathogenic mechanisms, and emerging therapeutic strategies targeting these cells. We highlight

Frontiers in Physiology, 2018 Spontaneous firing of sinoatrial (SA) node cells (SANCs) is regulated by cyclic adenosine monophosphate (cAMP)-mediated, protein kinase A (PKA)-dependent (cAMP/PKA) local subsarcolemmal Ca2+ releases (LCRs) from ryanodine receptors (RyR).

Effect of Quazodine on Phosphodiesterase
Experimental Biology and Medicine, 1971 SummaryQuazodine (6,7-dimethoxy-4-ethylquinazoline, MJ 1988) was up to 6 times as potent as theophylline in inhibiting PDE partially purified from a number of rabbit tissues and beef brain. As with theophylline, inhibition of PDE could be the underlying mechanism for the bronchodilator and cardiovascular effects of quazodine.

Pentoxifylline dose finding trial in preterm neonates with suspected late onset sepsis (PTX‐trial)
British Journal of Clinical Pharmacology, EarlyView.Aim The aim of this study (PTX‐trial) is to determine the optimal dose of pentoxifylline (PTX) in preterm neonates (gestational age < 30 weeks) with (suspected) late onset sepsis (LONS). Methods The PTX‐trial is a prospective multicentre open‐label sequential dose‐optimization study with an adapted continual reassessment method.

Spatiotemporal regulation of cAMP signaling controls the human trophoblast fusion
Frontiers in Pharmacology, 2015 During human placentation, mononuclear cytotrophoblasts fuse to form multinucleated syncytia ensuring hormonal production and nutrient exchanges between the maternal and fetal circulation. Syncytial formation is essential for the maintenance of pregnancy

Light‐Induced Anion Translocation to Control Helical Folding in an Artificial Communication System
Chemistry – A European Journal, EarlyView.Anion‐induced helical folding of an oligomer is controlled indirectly and reversibly by light through anion uptake/release by a photoresponsive receptor. Thus, a light signal is processed into a chemical signal in a communication‐type three‐component supramolecular system.
